It would seem to me that Hikari also contains more crude fat, less fiber and less crude protein. And it also has fillers, unless wheat is a natural source of food for fish. Not saying that Hikari is bad, just saying that it necessairily isn't any better than Wardleys, unless of course you can find other info, which may change my mind.
